The term "dramatis personae" in a play refers to the **list of characters** or the **cast list**. It provides a comprehensive list of all the characters that appear in the play. This list includes the main characters, supporting characters, and sometimes even minor characters. The purpose of including a dramatis personae is to help the audience or readers understand who the characters are and their roles in the story. It ensures that everyone involved in the production, such as actors, directors, and stage crew, is aware of the characters and their importance. In a nutshell, the dramatis personae is like a character reference guide, giving an overview of who is who in the play.
